Prefix Generate* LDH ops with ldh- for naming consistency

`GeneratePortal`, `GenerateClassContainers`, and `GenerateOntologyViews`
were the only ops under `linkeddatahub/` not registered with the `ldh-`
prefix used by their siblings. Add `name()` overrides, update the
example and README to match, and document a few previously unlisted ops
while at it.
